Location: The Sixtymile Butte prospect is a large area of about 12 square miles located within T. 20-21 N., R. 12-13 E., Tanacross (C-5) and (C-6) quadrangles, covering much of Sixtymile Butte. There are two centers of prospecting activity: one in the SE1/4 section 20, T. 21 N., R. 12 E., of the Copper River Meridian and the other in the SE 1/4 section 29, T. 21 N., R. 13 E., of the Copper River Meridian. The coordinates given are for the first location. The locations are accurate to within 1 to 2 miles.
Geology: The Sixtymile Butte area is dominated by mid-Cretaceous lavas, welded tuffs, tuff breccias and volcanic agglomerates (Foster, 1970). These rocks were mapped as Tertiary, but recent work suggests that they are Cretaceous (Doyon Ltd., 1998). The volcanics range in composition from andesitic to dacitic and have volcanic-arc-type, minor-element abundances (Bacon and others, 1990). Stream-silt sampling revealed three drainages with anomalous gold values (Doyon Ltd., 1998).
Workings: In 1975, WGM Inc. conducted a base-metal reconnaissance program. In 1981, Arctic Resources Inc. did a soils traverse, and in 1985 Doyon Ltd. resubmitted the samples for Au pathfinders. In 1990, Doyon Ltd. sampled stream sediments for gold.
Age: The volcanic complex probably is mid-Cretaceous (Doyon, 1998).
